问题是我将所有文件都上传到了我的域(公共html).
它肯定会加载页面，但子图像(徽标)无法加载.
我在代码中看到有一个loadurl(index.php?=text)
我需要创建页面index.php吗?
我不知道该怎么办.
有人可以帮我吗?
这是我的临时域的链接
http://75.126.247.111/~phildogb/ [ ^ ]
The problem is I uploaded all the files to my domain (public html).
It''s certainly load the page but the child images (the logo) can''t load.
I saw in the code that there is a loadurl(index.php?=text)
